Protection for house and garage
At home someone is rarely standing next to the charger. The box reacts by itself before a fire leaves the garage.
Application area
In the garage, cellar and home, e-bike, tool and household batteries are charged every day — often unattended and right next to the bike, tools and living space. The RUK Li-Ion Safety Box creates a closed, monitored charging place there.
Starting point

At home something is on charge almost every day: the e-bike after a ride, the tool battery after work, the power bank overnight. When that happens in the garage, charging often runs for hours with nobody watching.
Garage and cellar have become the charging place. Bike, workbench and batteries stand close together. Charging uses different devices, often overnight, with nobody in the room.
The socket is wherever it is convenient: on the garage wall, under the workbench, in the utility room. Private chargers are used as well, and their condition is rarely checked.
What matters is how close this is to where people live. A garage is part of the house. What happens during unattended charging decides the damage to the bike, the tools, the building and, in the worst case, to people.

How it works
The RUK Li-Ion Safety Box stands closed in the garage or cellar. Box S measures 600 × 400 × 450 mm, Box M 600 × 600 × 450 mm, with no conversion and no extra fire-protection room. Size L is currently being researched and developed.
E-bike, tool and household batteries are charged in the closed interior, instead of in the open next to the bike and the workbench.
Monitoring continues even when nobody is home and charging runs overnight.
In a critical state the box switches off by itself, raises the alarm and fights the fire before it leaves the box and spreads into the garage.
Benefits
At home someone is rarely standing next to the charger. The box reacts by itself before a fire leaves the garage.
E-bike, tool battery and power bank get one fixed charging place instead of several open cables on the garage wall.
Lowers the risk for people in the house and protects the bike, the tools and the building from a fire that starts in the garage.
Stands closed in the garage or cellar all year and stays ready, even if charging only happens in the evening or at the weekend.
In detail
| Typical situation | Risk without protection | With the RUK Li-Ion Safety Box |
|---|---|---|
| E-bike charges overnight in the garage next to the bike | Unattended fire right against the house | Closed box with monitoring and firefighting on its own |
| Nobody is home while charging | A fire in the garage goes unnoticed for a long time | Detection, alarm and firefighting on its own |
| Tool batteries charge in the open on the workbench | Several chargers, often with nobody watching | One closed charging place for the household batteries |
| Power banks and household batteries in the cellar or hallway | Charging without a defined safety environment | Closed charging in the box, IP54. Box S: 600 × 400 × 450 mm, Box M: 600 × 600 × 450 mm |
| Batteries, bike and tools stand in a tight space | Charging runs while the garage is closed | Closed box with a key switch |
| Everyday charging of e-bike, tools and household devices | Charging happens on the side, with no fixed check | Stays ready, even if charging only happens in the evening or at the weekend |
